There may be.

Putting fresh corn directly into the refrigerator will not cause any damage to the nutrition of the corn, but it will cause other problems. There are many bacteria in the refrigerator, especially psychrophilic bacteria, which can continue to grow and reproduce at temperatures of minus 20 degrees Celsius. Even if it is killed by high-temperature sterilization, it secretes a toxin that will not be destroyed even by high-temperature sterilization.

The toxins produced by psychrotrophic bacteria can cause serious intestinal diseases and are harmful to the body. Corn will also produce a toxin called "aflatoxin" during the freezing process, which is also harmful to human health. Even if you want to cook the corn and freeze it in the refrigerator, a lot of bacteria will be generated. The cooked food will deteriorate more easily and will be difficult to detect after freezing. Eating such corn is not good for the stomach.

Corn preservation tips:

If you want to preserve corn in the refrigerator, do not peel off all the corn husks you buy, but leave some. Then prepare a plastic bag, put the corn in the bag, and seal the bag tightly to ensure that the corn is not contaminated by bacteria when frozen. The second thing is to pay attention to the freezing time. Raw corn should not exceed 1 month, and cooked corn should not exceed 7 days, otherwise it will deteriorate.
